.Sta te olWVashington, have yinvented new. and

useful Improvements yin Cultivator Meehanism, of which the following is 'a specifi- This invention relates toV `improvements in wheeled frames forcultivating and :seedkingawith meanslor attachment thereto fofaiiy such earth treating devicesas may be neces -sary for the worlctobe performed.

The invention is especially designedfor i small work suclifasgarden or truokfwork and has to do with a wheeled` frame" which is adapted to .be horsedrawn. 1 In initially working the land for garden, wherethe rows are 4close togetheig'it is practically impossible to drive a horse inva straight line and f such deviations as the horsevdo'es make, are

i lail more pronounced .aridi troublesome 1in Q closely spaced garden rows than inthezmore widely spaced field rows'. Tlius, if in the initial working or cultivatingthe rows-are sinuous, then in seeding" and other following treatments, the initial sinuosityicrfirregularity of the rows must befffollowed inoty withstanding tli'el'fact thatI the horse cannot Abe' made to follow such deviations.

Therefore, itis 'a primary 'objeetfof this f in vention to provide a wheeled frame which is not Aonlyadapted tol be readilyy shiftedfto "cause the cultivating shovels: to vtrrwel in a straight line, irrespectiveof deviations by the`V horse, thereby' making the initial rows f as straight possible, but' in the "event that the initial rows are notfstraight, this shiftving* feature affords theoperator' means for following 'whatei'fer deviation there kis inthe rows during" the seeding and" other `earth y treatingk operations.'

` Whileit is 'noty lbroadlynew to provide forth, myfinvention increased. In vaccordance with my vinvention, it is not necessary 'to wait Vfor the ground `wheels to]` actually "swerve and theiitale a` new lateral path of travel before the'frame can' shift the' earthfworking devices', on the "contrary, iny improved fram-e vcante shifted and tlie ground wheels will pivot on the time to- 'materially travel.L

whereby the frame will be supported on vsaid` axles. Said vertical sections terminate in,

forwardly 1 projecting steering sections 6 which are link connected by a link 7,.-p1voted to saidsections-at'8.y

I will next refer to the framel and to the is shiftably lar frame portion which is rearwardly dis- .i

posed and which may comprise horizontal upper and lower members 9 and 10, united by vertically disposed members 11. The exact construction of this frame is vnot material to thisinvention and may be varied as requirements dictate. I have shown the sections 4, jouinaled or swiveled through or in this frame portion, said sections extending through the members 9V and 10 along side of theverticalmembers 11, the latter having bearings 12 through which said section-s extend. Collars 13 supportthe frame on said axles against downward sliding movement. The exact manner in which the frame is swiveled to the axles, to be supported thereby, is not important and may be varied within the limitations ofthe claims. The important feature is that the frame is supportedonthe axles, for one thing, and that in addition to being supported on the axles, the frame is swiveled thereon.`

I have shown the frame constructed for one horse draft by reason of they fact that this mechanism is especially designed for` garden or truck work, andtherefore, shafts 14 are secured to the frame at 15, and extend forwardly in converging relation, as shown. Secured to the shafts 14, is 'a frame member 16, which with the frame portion heretofore described, and the shafts, forms a rigid frame structure. -Depending from the frame member 16, are pairs ofhangers 17, the lower endsof which form bearings for spindles 18 on which the forwardV ends 19, are journaled. I have shown cultivating shovels 20, as being attachedgto the' frame, the ends19 forming theterminals of the beams 21'.l However, `I have Vreferred to these shovels as earthtreating devicesbecause the device of my invention is equally adapted for use'in connection with'seeders or any earth treating implement that might be used in trucking of this character. A

. drivers seat`22, is mounted ona resilient bar 23vwhich is secured at 24, to member 9, and

at25, to member `16.

Steering means is next be' described.

As shown, a steering or shifting lever 26,

provided which will is pivoted at 27, to frame member 16, the

handle end 28 being in easy reach of the drivers seat 22. A link 29, is pivoted at 30, to lever 26, andat 31, to the right hand section 6. I have not shown a quadrant lock for the lever 26 as in practice, the lever is almost constantly being used and if desired, any suitable retainer for holding the lever 26 in a straight draft position, may be em` ployed. Braces 32 may-be `employed to steady the hangers 17, as shown in Fig. 1

vmovement vof the wheels into a new or Now it will be clear that if the lever is shifted in either ofthe directions indicated by the arrow, the ground wheels 1 will pivot about their ground engaging peripheries as shown in dotted lines, the turning thrust on the axles causing the frame to swivel on the vertical sections 4, as the frame shifts laterally.V The leverage afforded by the relatively long sections 3 and 6, greatly facilitating this shifting movement. i Further, it is because of the relatively great length of the axle sections 3, that such a quick `and sweeping shifting` movement of the frame can be obtained. This leverage of the axle sections 3,.will readily cause the ground wheels to pivot on their supporting areas against such resistance as the ground may offer to such turning movement. The draft o n the frame, will normally act to assist in y son of the important fact that shifting movement of the frame `need not await latiral ateral pathof travel.

It is believed that the advantages of my invention will be fully understood from the foregoing description, and while I have shown one form oil` my invention.. I do not movement of the lever 26, andevenifthe y machine were-inv a position of rest, by reawish to be limited thereto except for such limitations as the claims may import.
